Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Kamran Bhatti - PeerSpot reviewer
Provides reliable real-time email protection and offers competitive pricing features
Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Enables me to work from two locations."
"The solution has different options that can be used to differentiate DDoS attacks."
"The blocking feature is very good."
"Clover is the best product globally."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare, in my opinion, was easy to implement."
"This solution is easy to understand and easy to configure."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature is the straightforward setup."
 

Cons

"For the topic of improvement, providing some training material is one of my suggestions."
"Our customers no longer use Cloudflare because its service is subpar."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The initial onboarding was causing us some confusion."
"Lacks a VPN feature to provide a secure connection to the data center."
"The onboarding process can be improved a little bit."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"The solution is not 100 percent stable and that can use improvement."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
 

Pricing and Cost Advice

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"My company makes annual payments towards the licensing costs solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution is not expensive."
